In fusion welding, thermal cycle leads to undesirable metallurgical structure and causes residual stresses gets induced near the weld zone which plays an important role in determining the reliability of the weld joint. In this present work, the prediction of residual stresses in a welded joint has been done using Contour method. The measurements of the cross-sectional residual stress profile in a Duplex stainless steel 2205 welded with ER 2209 filler material are validated in the longitudinal direction. This method is simple in principle and easy in use. According to this method, the weld metal containing residual stresses is cut along the plane perpendicular to the weld line. The deformations occurring at the cut surfaces as a result of relaxation of the residual stresses are measured. The measured deformations are given as displacement boundary conditions to a finite element model to calculate the corresponding stresses normal to the cutting plane.
